A new type of antibiotic uses DNA to fight a common deadly microbe, Clostridium difficile. These new drugs are inexpensive and adaptable and can be modified to target any bacterium, lowering the chance of drug resistance.

Bacteria exchange genes easily, but a newly discovered set of rules that regulate these exchanges could help us to prevent the spread of antibiotic resistance.

The discovery of molecular rules that regulate the transfer of genetic material between bacteria could help prevent the spread of antibiotic resistance.

Cattle that are grass-fed, antibiotic- and growth hormone-free gather at a farm in Oregon in 2015. There’s a debate over whether antibiotic use in livestock makes germs more resistant to the drugs, and results in infections being passed on to humans who consume the meat.

Antibiotic-munching microbes may prove useful for mopping up contaminated water supplies and land.

Research shows potential for delivering our drugs in ways that would make it harder for antibiotic resistance to evolve and spread. Here we see a close up view of a biofilm of antibiotic-resistant bacteria.

Pharmaceutical companies focus on small molecules they've devised – and can easily patent. But nature's already come up with many antibacterial compounds that drug designers could use to make medicines.

Researchers are using epigenetics to find ways to 'turn off' bacteria's ability to cause infections.

New Zealand researchers have found that the active ingredients in commonly-used weed killers like Round-up and Kamba can cause bacteria to become less susceptible to antibiotics.
